Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines Rahmens nach dem Oberbegriff des Patentanspruchs.The invention relates to a method for manufacturing a frame according to the preamble of the claim.

Bei einem derartigen als bekannt vorausgesetzten Verfahren besteht das Problem, daß die Biegekante zwischen dem an der Trittfläche der Platte liegenden Schenkel einerseits und dem die Seitenkante der Platte bildenden Teil des Rahmenbleches andererseits nicht scharfkantig, sondern lediglich abgerundet mit einem Radius von mindestens etwa 1 mm herstellbar ist. Dadurch bildet sich bei einem Aneinanderliegen der Platten ein entsprechend großer Spalt, der in der Praxis unerwünscht ist. Besonders störend wirkt sich dieser Spalt aus, wenn die Bodenplatten mit einem dünnen Hartbelag als Trittflächenbelag versehen werden. In solchen Fällen kann es nämlich passieren, daß der Hartbelag durch Belastung, z.B. durch auf diese Stelle mit Pfennigabsätzen auftretende Damen, einbricht. Diese Gefahr besteht vor allem in den Bereichen der Plattenkanten.In such a method, which is assumed to be known there is the problem that the bending edge between that lying on the tread of the plate Leg on the one hand and the side edge of the plate forming part of the frame plate on the other hand not sharp-edged, but only rounded off with can be produced with a radius of at least about 1 mm is. This forms when they lie against each other of the plates a correspondingly large gap that in the Practice is undesirable. Is particularly disruptive this gap from when the floor slabs with a thin hard surface can be provided as a tread surface. In such cases it can happen that the hard surface due to stress, e.g. through on this Place ladies appearing with stiletto heels, breaks in. This is particularly a danger in the areas the plate edges.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art anzugeben, nach dem Rahmen erreichbar sind, die beim Zusammenfügen der Bodenplatten nicht zu einem störenden Spalt zwischen diesen führen.The invention is therefore based on the object  To specify procedures of the type mentioned at the beginning, according to the frame can be reached when merging the floor plates do not form an annoying gap between lead this.

Diese Aufgabe wird durch ein Herstellverfahren mit den im kennzeichnenden Teil des Patentanspruchs angegebenen Merkmalen gelöst.This task is accomplished through a manufacturing process the specified in the characterizing part of the claim Features resolved.

Ein Ausführungsbeispiel ist in der Zeichnung darge­ stellt. Es zeigAn embodiment is shown in the drawing poses. It shows

Fig. 1 einen Schnitt durch ein vorgeformtes Rahmenblechprofil als Ausgangsprofil für das erfindungsgemäße Umformverfahren, Fig. 1 shows a section through a pre-formed frame plate profile as the starting profile for the inventive forming method,

Fig. 2 das Blechprofil nach Fig. 1 eingespannt in ein Umformwerkzeug, Fig. 2, the sheet profile according to Fig. 1 clamped in a forming tool,

Fig. 3 einen Schnitt durch das fertiggeformte Rahmenprofilblech mit rechtwinkliger Oberkante. Fig. 3 shows a section through the fully formed frame profile sheet with a rectangular upper edge.

Das Blechprofil 1 besitzt U-förmige Grundform. Nahe der Biegekante 2 ist eine Längssicke 3 in das Blechprofil 1 eingeformt.The sheet profile 1 has a U-shaped basic shape. A longitudinal bead 3 is formed in the sheet metal profile 1 near the bending edge 2 .

Zur Ausbildung einer exakt rechteckigen Biegekante 2 wird das Blechprofil 1 in ein Verform-Werkzeug eingespannt. Dieses Werkzeug besteht im einzelnen aus einer Aufnahme 4, einer Niederhalteplatte 5 und einer Druckplatte 6. Um die Sicke 3 einzuebnen und damit einen Materialfluß in Richtung der Biegekante 2 zu bewirken, wird das Werkzeug wie folgt betätigt:To form an exactly rectangular bending edge 2 , the sheet profile 1 is clamped in a shaping tool. This tool consists in detail of a receptacle 4 , a hold-down plate 5 and a pressure plate 6 . The tool is operated as follows in order to level the bead 3 and thus cause a material flow in the direction of the bending edge 2 :

Das Blechprofil 1 wird mit seiner Innenkontur in die Aufnahme 4 eingelegt und mit der Niederhalteplatte 5 festgeklemmt. Mit der Druckplatte 6 wird die Sicke 3 planeben so verformt, daß die Auswölbung der Sicke 3 in Richtung der rechtwinkligen Biegekante 2 fließt.The sheet profile 1 is inserted with its inner contour into the receptacle 4 and clamped with the hold-down plate 5 . With the pressure plate 6 , the bead 3 is deformed plane so that the bulge of the bead 3 flows in the direction of the right-angled bending edge 2 .

Das fertige Blechprofil 1 mit einer tatsächlich rechtwinkligen bzw. rechteckigen Biegekante 2, bei dem die Sicke 3 eingeebnet ist, zeigt Fig. 3.The finished sheet profile 1 with an actually rectangular or rectangular bending edge 2 , in which the bead 3 is leveled, is shown in FIG. 3.
